Edoxaban Treatment in Routine Clinical Practice for Patients With Non-valvular Atrial Fibrillation (ETNA-AF-Hong Kong)

Non-interventional Study on Edoxaban Treatment in Routine Clinical Practice for Patients With Non-valvular Atrial Fibrillation (ETNA-AF-Hong Kong)

In order to understand the risks and benefits of edoxaban use in a real-world clinical setting in the NVAF indication, Daiichi-Sankyo Hong Kong proposed this non-interventional study (NIS) to gain insight into the safety of edoxaban use in non-preselected patients with NVAF.

Study Overview

• Status: Completed
• Conditions: Atrial Fibrillation
• Intervention / Treatment: Drug: Edoxaban

Detailed Description

Edoxaban was approved by the Pharmacy and Poisons Board in Hong Kong (date: 31 May 2016) for the: Prevention of stroke and systemic embolism in adult patients with nonvalvular atrial fibrillation (NVAF) with one or more risk factors, such as congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke or transient ischemic attack (TIA). Treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE), and prevention of recurrent DVT and PE in adults.

In order to understand the risks and benefits of edoxaban use in a real-world clinical setting in the NVAF indication, Daiichi-Sankyo proposed this non-interventional study (NIS) to gain insight into the safety of edoxaban use in non-preselected patients with NVAF.

Real world evidence from routine clinical practice using edoxaban up to 2 years will be collected and evaluated in approximately 200 patients, treated by specialized as well as non-specialized physicians in hospital centers.

• Genders Eligible for Study: All

• Sampling Method: Non-Probability Sample

Study Population

Primary strategy is to include only patients with NVAF who are to be treated with edoxaban according to Package Information (Summary of Product Characteristics (SmPC)). To ensure that the physician's prescribing behaviour will not be influenced, patients may only be included after the treating physician has made the clinical decision to prescribe edoxaban. Patients must have provided written informed consent for participation in the study (ICF) and should not participate simultaneously in any interventional study.

Description

Inclusion Criteria:

• Is a NVAF-patient whose physician has made the clinical decision to prescribe edoxaban therapy according to Package Information
• Has provided written informed consent to participate in the study

Exclusion Criteria:

• Is participating in an interventional study
